Bradley,
Have you reviewed your decree for terms regarding the communication between you and the children? Sometimes there are provisions under the "legal custody" section. As a general matter, a parent cannot deprive the other parent contact with the children, although if they have other means of communication with you (a land line?), her actions may not be viewed as prohibited.
If she continues to block them, you could seek a modification of the original decree regarding visitation and communication to provide that she cannot interfere with your relationship with them.
If you would like assistance, please call me at 525-245-4300.
